How to change language mode of VSCode programmatically?
typescript, visual-studio-code, vscode-extensions
Solution
Currently this is not possible. Here is the corresponding issue on GitHub. You should upvote (thumbs up) it to tell them we want this.
Problem
I have tried `vscode.commands.executeCommand('workbench.action.editor.changeLanguageMode', 'JSON');`. But it does nothing more than open a panel. And `TextDocument.languageId` is an readonly property.
